DIAGNOSTIC PROCEDURE CHART

Step Check Yes No
1 CHECK VEHICLE SPEED SIGNAL.

  3. Measure the voltage between combination meter connector and chassis ground.

    Connector & terminal 

    (i10) No. 19 (+) - Chassis ground (-): 

 Is the voltage less than 1 V ↔ 5 V or more? Replace the meter case assembly. Go to step 2.
